Through 2024 and 2025 a quiet rebalancing happened: password-phishing fell, session-cookie theft via infostealers surged, and “we have MFA” stopped meaning what defenders thought it meant. A 2026 field guide to the technique and the controls that actually answer it.
Browsing: Stealer Logs
Coverage of infostealers, credential markets, and the stealer-log economy.
A 2026 walkthrough of the typical infostealer-log archive — what files it contains, what each one means, and how defenders parse them with Python and jq for downstream incident response.
A practitioner’s tutorial for checking whether your email, your domain, or your employees show up in fresh infostealer logs — using Hudson Rock’s free tools, IntelX, Have I Been Pwned, and a couple of paid options worth the spend.
A 2026 tutorial on building a layered defence against infostealers — endpoint EDR settings that catch stealer behaviour, browser hardening that protects cookie stores, and the user-side training that closes the actual gap.
Stolen credentials are only half the package. The other half is the browser fingerprint that lets an attacker impersonate the victim’s session believably. A 2026 look at how fingerprint markets work.
A practitioner’s look inside the “cloud of logs” subscription model — what attackers pay, what they get, and the operational mechanics that turn raw infostealer output into a productised threat.
Stealing your password used to be the goal. In 2026 it’s the consolation prize — modern infostealers go for session cookies, which let attackers impersonate authenticated users without needing to defeat MFA. Here’s how the model works.
A 2026 comparative profile of the three dominant infostealer families — capabilities, distribution channels, market share by observed infections, and where each is heading after the 2024 takedown actions.
A practitioner’s forensic playbook for working backwards from a stealer log to the originating infection — what the log file structure tells you, where the malware sits, and how to clean it up properly.
Newsroom and researcher checklist for validating a leaked dataset before publishing — five tests that catch fabrication, recycled breaches, and misattributed dumps.
